2007 Subaru Impreza WRX STi cold air intakes by K&N come with a high-flow washable air filter designed to perform for the life of your vehicle. K&N Subaru Impreza WRX STi cold air intake kits come with a million mile limited warranty.

Really great product and well worth the price, dramatically increases power, throttle response, and turbo sound. Everything fits great, but make sure you have all the listed tools. Took me about two hours to install without the ratchet extension. Thanks K&N
